MS has had people complaining since MS-DOS 5.0. Quarterdeck was mad because of the memory management and makers of defragmenters were mad because of the built in defragmenter.
Before that you used to have top buy everything seperate. They were good programs for the time, but you could spend serious money on utilities that now come with the operating system.
In a lot of ways XP is the best OS MS has ever made but after having bought 95 and 98 and ME I think it is abou time they got it right.
